From: Formation mechanism and optimization of highly luminescent N-doped graphene quantum dots
Representative TEM images (A–C), SPM images (D–F) and XPS spectra (G–I) of GQDs-HMTA, GQDs-DEA and GQDs-EA.
Left and right insets are the corresponding HR-TEM images and particles size distribution in A–C. The height profiles in D–F are inserted along the line cut. High resolution C 1s and N1s spectra are inserted in the full scan survey in G–I.
